“It’s no great secret that sometime before Christmas I’m going to have a conference with Churchill and Stalin. Not that I’ve any clue where that will be. Stalin has rejected coming to London, so we could wind up almost anywhere. But wherever we end up meeting I want to have a clear idea on this Katyn Forest situation, because it seems certain to affect the future of Poland. The Russians have already broken off diplomatic relations with the Polish government in London. The British, of course, feel a special loyalty to the Poles. After all, they went to war for Poland. So, as you can see, it’s a delicate situation.”

The president lit another cigarette and then rested a hand on the bundle of files.

“Which brings me to you, Professor Mayer. I want you to conduct your own investigation into these Katyn Forest claims. Start by making an objective assessment of what the files contain, but don’t feel you have to limit yourself to them. Speak to anyone you think would be of use. Make up your own mind and then write a report for my eyes only. Nothing too long. Just a summary of your findings with some suggested courses of action. I’ve cleared it with Donovan, so this takes priority over anything else you’re doing.”

Taking out his own handkerchief, he wiped his hand clean of dust, and didn’t touch the files again.

“How long do I have, Mr. President?”

“Two or three weeks. It’s not long, I know, for a matter of such gravity, but as you can appreciate, that can’t be helped. Not now.”

“When you say ‘speak to anyone who might be of use,’ does that include people in London? Members of the Polish government in exile? People in the British Foreign Office? And how much of a nuisance am I allowed to make of myself?”

“Speak to whomever you like,” insisted Roosevelt. “If you do decide to go to London, it will help if you say that you’re my special representative. That will open every door to you. My secretary, Grace Tully, will organize the necessary paperwork for you. Only, try not to express any opinions. And avoid saying anything that will make people think you’re speaking in my name. As I said, this is a very delicate situation, but whatever happens, I’d very much like to avoid this coming between myself and Stalin. Is that clearly understood?”
